二滩水电站拱坝坝肩岩体稳定性的地质力学模型试验中的声波测试

为了获得模型体内关键部位的应力、应变的变化与分布规律, 特别是外荷载作用下的安全区域, 我们利用自行设计的小型传感器, 首次将声波测试技术应用到较大型的模拟实验室中。获得了试验全过程的测试结果。其结果与其它测试方法, 互为补充和验证, 得到了一致的预期效果。

ACOUSTIC MEASUREMENT IN GEOMECHANICAL MODELING EXPERIMENT OF ARCH DAM ABUTMENT ROCKMASS STABILITY FOR ERTAN HYDROELECTRIC

In order to obtain the variation and distribution properties of stress and strain at the key parts of a model, especially at the safe area from an external burden, we first apply the acoustic testing to the comparatively large model experiment using the small-size sensors developed by ourselves. We obtained the testing results during the whole experiment process. The results and those from other testing methods are complement and verification to each other. The identical expecting results are obtained.
